Margaret E. Knight
Margaret Eloise Knight (February 14, 1838 – October 12, 1914) was an American inventor, notably of a machine to produce flat-bottomed paper bags. She has been called "the most famous 19th-century woman inventor". She founded the Eastern Paper Bag Company in 1870, creating paper bags for groceries similar in form to the ones that would be used in later generations. Knight received dozens of patents in different fields, and became a symbol for women's empowerment. Early life Margaret E. Knight was born in York, Maine on February 14, 1838, to Hannah Teal and James Knight. As a little girl, “Mattie,” as her parents and friends nicknamed her, preferred to play with woodworking tools instead of dolls, stating that “the only things hewanted were a jack knife, a gimlet, and pieces of wood.” She was known as a child for her kites and sleds. Knight and her brothers, Charlie and Jim, were raised by their widowed mother; Knight's father died when she was young, after which the ...

York, Maine
York is a town in York County, Maine, United States, near the southern tip of the state. The population in the 2020 census was 13,723. Situated beside the Atlantic Ocean on the Gulf of Maine, York is a well-known summer resort town. It is home to three 18-hole golf clubs, four sandy beaches, and Mount Agamenticus. It includes the villages of York Village, York Harbor, York Beach and Cape Neddick. York is part of the Portland– South Portland–Biddeford, Maine metropolitan statistical area. History First settled by Europeans in 1624, the plantation was originally called Agamenticus, the Abenaki term for the York River. In 1638, settlers changed the name to Bristol after Bristol, England, from which they had immigrated. Envisioning a great city arising from the wilderness, Sir Ferdinando Gorges, lord proprietor of Maine under the Plymouth patent, named the capital of his province Gorgeana. On March 1, 1642, by charter of King Charles I, Gorgeana became the first incorpora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuttle (weaving)
A shuttle is a tool designed to neatly and compactly store a holder that carries the thread of the weft yarn while weaving with a loom. Shuttles are thrown or passed back and forth through the shed, between the yarn threads of the warp in order to weave in the weft. The simplest shuttles, known as "stick shuttles", are made from a flat, narrow piece of wood with notches on the ends to hold the weft yarn. More complicated shuttles incorporate bobbins or pirns. In the United States, shuttles are often made of wood from the flowering dogwood, because it is hard, resists splintering, and can be polished to a very smooth finish. In the United Kingdom shuttles were usually made of boxwood, cornel, or persimmon. Flying shuttle Shuttles were originally passed back and forth by hand. However, John Kay invented a loom in 1733 that incorporated a flying shuttle. This shuttle could be thrown through the warp, which allowed much wider cloth to be woven much more quickly and made the develo ...

Blueprint
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey. The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers. The term ''blueprint'' continues to be used less formally to refer to any floor plan (and even less formally, any type of plan). Practicing engineers, architects, and drafters often call them "drawings", “prints”, or “plans”. It has almost entirely been replaced with digital computer-aided ...

American Society Of Mechanical Engineers
The American Society of Mechanical Engineers (ASME) is an American professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, an advocacy organization, a provider of training and education, and a nonprofit organization. Founded as an engineering society focused on mechanical engineering in North America, ASME is today multidisciplinary and global. ASME has over 85,000 members in more than 135 countries worldwide. ASME was founded in 1880 by Alexander Lyman Holley, Henry Rossiter Worthington, John Edison Sweet and Matthias N. Forney in response to numerous steam boiler pressure vessel failures. Kno ...

Smithsonian (magazine)
''Smithsonian'' is the official journal published by the Smithsonian Institution in Washington, D.C. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life (magazine), Life'' magazine, was asked by the then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian [Institution] is interested, might be interested or ought to be interested." Thompson would later recall that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning the ...

Prejudice
Prejudice can be an affective feeling towards a person based on their perceived group membership. The word is often used to refer to a preconceived (usually unfavourable) evaluation or classification of another person based on that person's perceived political affiliation, sex, gender, gender identity, beliefs, values, social class, Ageing, age, disability, religion, sexual orientation, sexuality, Race (human classification), race, ethnicity, language, nationality, culture, complexion, beauty, height, body weight, job, occupation, wealth, education, criminality, Fan loyalty, sport-team affiliation, Psychology of music preference, music tastes or other personal characteristics. The word "prejudice" can also refer to unfounded or pigeonholed beliefs and it may apply to "any unreasonable attitude that is unusually resistant to rational influence". Gordon Allport defined prejudice as a "feeling, favorable or unfavorable, toward a person or thing, prior to, or not based on, actual ex ...

Interference Proceeding
An interference proceeding, also known as a priority contest, is an inter partes proceeding to determine the priority issues of multiple patent applications. It is a proceeding unique to the patent law of the United States. Unlike in most other countries, which have long had a first-to-file system, until the enactment of the Leahy-Smith America Invents Act (AIA) in 2011, the United States operated under a first-to-invent. The interference proceeding determines which of several patent applications had been made by the first inventor. The AIA switched the US to a first-to-file regime effective March 16, 2013, and interferences apply only to patent applications with an effective filing date prior to that change. Definition An interference proceeding is an administrative proceeding conducted by a panel of administrative patent judges (administrative law judges sitting on the Board of Patent Appeals and Interferences) of the United States Patent and Trademark Office (USPTO) to det ...

Francis Wolle
Francis Wolle (December 17, 1817 in Jacobsburg, Pennsylvania – 1893 in Bethlehem, Pennsylvania) was an American priest of the Moravian Church, inventor and phycologist. Francis Wolle invented the first bag-making machine in 1851, forming the basis for the Union Bag and Paper Company. Wolle patented his "Machine for Making Bags of Paper" in 1852. In his words, "pieces of paper of suitable length are given out from a roll of the required width, cut off from the roll and otherwise suitably cut to the required shape, folded, their edges pasted and lapped, and formed into complete and perfect bags." The machine produced 1,800 bags per hour. He patented a more elaborate machine in 1855, and a third in 1858 with a provision "for preventing the loss of the strips of paper usually cut off in order to make the bottom lap or seam of the bag." This last feature prevented those strips from jamming the machine. Wolle's bags were folded similarly to aerograms; several tablike edges were fold ...

Printing Press
A printing press is a mechanical device for applying pressure to an inked surface resting upon a printing, print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed repeatedly to achieve the transfer of ink, and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. In Germany, around 1440, goldsmith Johannes Gutenberg invented the movable-type printing press, which started the Printing Revolution. Modelled on the design of existing screw presses, a single Renaissance movable-type printing press could produce up to 3,600 pages per workday, compared to forty by History of typography in East Asia, hand-printing and a few by scribe, hand-copying. Gutenberg's newly devised matrix (printing), hand mould made possible the precise and ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upholstery
Upholstery is the work of providing furniture, especially seats, with padding, springs, webbing, and fabric or leather covers. The word also refers to the materials used to upholster something. ''Upholstery'' comes from the Middle English word ''upholder'', which referred to an artisan who makes fabric furnishings. The term is equally applicable to domestic, automobile, airplane and boat furniture, and can be applied to mattresses, particularly the upper layers, though these often differ significantly in design. A person who works with upholstery is called an ''upholsterer''. An apprentice upholsterer is sometimes called an ''outsider'' or ''trimmer''. Traditional upholstery uses materials like coil springs (post-1850), animal hair (horse, hog and cow), coir, straw and hay, hessians, linen scrims, wadding, etc., and is done by hand, building each layer up. In contrast, today's upholsterers employ synthetic materials like dacron and vinyl, serpentine springs, and so on. Histor ...

Engraving
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning th ...
